High pressure fresh water wash or fresh water wash, as appropriate,
and remove all oil or grease, soluble contaminants and other
foreign matter in accordance with SSPC-SP1 solvent cleaning. All
surfaces to be coated should be clean, dry and free from
contamination.

Newbuilding

Remove weld spatter and smooth weld seams and sharp edges. The
surfaces should be blast cleaned to Sa2.5(GB/T 8923.1-2011).The
weld seams areas could be cleaned to St3(GB/T 8923.1-2011)using
power tool.

Apply 725-H45-66 before oxidation occurs. If oxidation has
occurred, the entire oxidized area should be reblasted to the
standard specified above.

Repair/On Board Maintenance

The areas to be repaired should be cleaned to St3(GB/T
8923.1-2011)by mechanical method or higher level of surface
prepared to Sa2.5(GB/T 8923.1-2011)by abrasive blasting. Abrade the
area immediately surrounding the repair to provide a key for
subsequent coating application. Overlap areas should be kept to a
minimum.

Limitations

This product will not cure adequately below 5℃. For maximum
performance ambient curing temperature should be above 10℃

In common with all epoxy base coatings, 725-H45-66 will exhibit
chalking of the firm on UV exposure.

Apply in good weather. Temperature of the surface to be coated must
be least 3℃ above the dew point when the humidity is lower than
85%.

The dry time and overcoating interval may change according to the
environment factors.

Avoiding absorb the solvent steam and paint steam for long time.
Skin and eyes must avoid contacting the paint. Pay attention to
